Answer:

x=-12

Step-by-step explanation:

x^2-24x+144=0

When you see it as =0, that doesn't mean it's 0. it means it needs more deep solving.

x^2+24x+144-144=0-144

x^2+24x=-144

x^2+24x+12^2=-144+12^2

x^2+24x+12^2=0

(x+12)^2=0

x+12=0

x=-12

Answer:

x = 12

Step-by-step explanation:

Step 1: Write quadratic

x² - 24x + 144 = 0

Step 2: Factor

(x - 12)(x - 12) = 0

Step 3: Find roots

x - 12 = 0

x = 12

Hello!
The left triangle have two same side length so the two bottom angles are the same which is (180-56)/2=62
See the left triangle bottom right angle and the right triangle bigger angle have the sum of 180 degree so the bigger angle=180-62=118
The right triangle also have two same sides so they also have same angle degree so x=(180-118)/2=31
Have a great day!

The graph below represents an employee's earnings based on units sold. What can be interpreted from the slope of this graph?

Vesna [10]

Answer:

Step-by-step explanation:

From inspection of the graph, we can see that every time the x-value increases by 10, the y-value increases by 1000.

So, the employee earns an additional $1000 for every 10 units sold.

To calculate how much the employee earns for every 1 unit sold, divide $1000 by 10:

1000 ÷ 10 = 100

Therefore, the employee earns an additional $100 for every one unit sold.

Proof

This can be proved by calculating the slope (gradient) of the graph:

$\sf slope=\dfrac{y_2-y_1}{x_2-x_1}$

where $\sf (x_1,y_1)$ and $\sf (x_2,y_2)$ are two points on the line

When picking the two points, remember that the y-values are in thousands of dollars.

Two points on the line:

(0, 30000) and (20, 32000)

Substituting these into the formula:

$\sf \implies slope=\dfrac{32000-30000}{20-0}=\dfrac{2000}{20}=100$

Therefore, the employee earns an additional $100 for every one unit sold.

During which section of the car's trip is the moving at the fastest speed?

Ganezh [65]

The answer is C. I think we can agree that it would be between C and D because they look steeper than A and B. The slope of C is 3 and the slope of D is 2 and 3 is more, so C is your answer.
